channel. These two reference channels can carry out mutual simple math calculation between each
other. And the reference channels can be shifted dynamically through set multi-funciton terminals.
There are three assistant reference channels: keypad UP/DOWN input, terminals UP/DOWN switch
input and digital potentiometer input. The three ways equal to the effect of input UP/DOWN reference
in internal assistant reference of the inverter. The user can enable the reference method and the
effect of the method to the frequency reference by setting function codes.
The actual reference of the inverter consists of main reference channel and assistant reference
channel.
